DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 544,249, dated August 6, 1895.

Application filed April 4, 1895-,

To all whom it may concern.-

Be it known that 1, WILLIAM M. DUNMAN, a resident of Rusk, in the county of Cherokee and State of Texas, have invented certain new and useful Improvements in Dumping- Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in cars, and more particularly to dumping-cars, one object of the invention being to produce a dumping-car which can be operated by two men to discharge its contents with a comparatively small amount of exertion on the part of the operators.

A further object is to so construct a car that it can be employed for conveying gravel, &c., which can be readily and quickly dumped or discharged therefrom, and to so construct the car that it can be readily adapted for carrying large freight of any description.

A further object is to so construct a car that its contents can be discharged at one or both sides thereof, as desired.

A further object is to provide means whereby to cause the contents of a car to be discharged automatically when the side of the car is raised.

A further object is to provide simple and elficient means for raising and lowering the sides of the car.

Afurther object is to providea car having movable sides with means whereby to reduce the friction to a minimum when said sides are raised or lowered.

A further object is to provide a dumpingcar with simple means whereby to reduce the friction of all the movable parts of the car.

A further object is to'produce a dumpingcar which shall be simple in construction, cheap to manufacture, easy to manipulate, and which shall be effectual in all respects in the performance of its functions.

With these objects in 'view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure l is a side View. Fig. 2 is a plan View. Fig. 3 is Serial No. 544,447. (No model.)

alongitudinal sectional view showing thefalse bottom removed and supported parallel with the inner face of the side of the car. Fig. 4 is a cross-section of the car with the false bottom in place. Fig. 5 is an end view. Figs. 6 and 7 are detail views.

A represents the car-bottom, which will be mounted on axles'in any suitable manner and preferably provided on its under side with a boot A for the reception of certain contrivances and other devices which it may be desired to place therein when not in use.

The ends B B of the car are provided with bars a, which project somewhat below the lower edges of said end pieces and enter sockets made in the car-bottom A. The sides 0 O, which project at both ends beyond the ends B B of the car, are supported in their vertical position by means of standards I) b b, secured to the car-bottom, and by the ends B. Each standard I) is provided with bracing plates or strips 1), and in theinner faces of said standards sockets are made for the reception of steel bearing-plates 5 in which latter small rollers c are mounted and adapted to roll on iron or steel strips a, secured to the sides 0, whereby to reduce friction when the sides are raised or lowered. Perforated arms 0 are socured to'the ends B of the car, and through said arms rods or bolts 0 are passed, said rods or bolts bearing at their lower ends on the plat forms A of the car.

The ends of the sides 0 G of the car are made with slots at, and at opposite sides of each slot (1 brackets d are secured for the reception of a pin d which pivotally connects a swinging latch D to said brackets. The latches D,'which are adapted to swing through the slots 01' and become disposed parallel with the outer faces of the ends B of the car, are made at their free ends with slots (1 for the accommodation of the rods or bolts 0 Each swinging latch D is provided, at or near the outer end of the slot at therein, with a roller d adapted to roll on the rods or bolts 0 and thus reduce friction between said latches and rods or bolts when the sides C O are raised or lowered. Bars or standards 6 are secured to the cute faces of the sides 0 O of the car, and 'projecting below thelower edges thereof pass through notches e in the car-bottom and through brackets c secured to the latter. In each bracket 2 two (more or less) rollers e are mounted and adapted to roll on metallic strips a, secured to the bars or standards e, and serve to assist in reducing friction when the sides C C are raised or lowered.

The car-bottom A is provided with sockets f for the reception of pins f,projecting from the lower edges of a series of (three, more or less) brackets g, each bracket being made with two beveled edges 9 g, inclining toward the sides 0 C of the car. On the brackets g a sectional false bottom E is located. The false bottom E comprises two parts h h, and to each part 71 a narrow section It is connected, preferably by means of strap-hinges h The car-bottom A is provided with a'series of notches 1', preferably lined with metal 2". Feetjare pivotally connected between ears j, secured to the under faces of the sections 71. of the false bottom, each foot being made with a shoulder or beveled upper end j (shown in dotted lines, Fig. 4) to limit its pivotal movement and to cause said feet, when the pertions h of the false bottom are raised to a horizontal position, to enter the notches or recesses 2'. When the false bottom is in its normal or horizontal position, as shown in Fig. 4, ready to receive and support the gravel or other material to be loaded into the car, the portions h will be disposed in a horizontal position and supported by the feet 3' and by the sides of the car-body, the feet resting at an angle, so that when the side of the car-body is raised the weight on the false bottom causes the section thereof thus released to fall or slide outwardly under the side which has been elevated until it comes to a rest on the inclined surfaces g of the parts g. The narrow hinged strips h, (which are beveled 011 their free edges,) when the parts are in their normal position, meet in the center, each holding the other in position and forming a sort of V- shaped projection in the center of the carviz., centrally between the sides thereof. Each section 7L of the false bottom is provided atits outeredge with rollers 7c, adapted to roll on metallic strips 7c, secured to the sides 0 of the car, whereby to assist in reducing friction when the sides are raised or lowered and to prevent the engagement of the false bottom with the sides of the car, which engagement, were it permitted, might mar the said sides 0 C.

Vhen the false bottom E is first placed in the car the portions h 72. thereof will lie on the inclined faces or edges of the brackets g and will afterward be raised to a horizontal position, as above explained, by means of suitable hooks, which latter are made to engage metallic eyes k secured to said sections h of the false bottom E.

Before explaining the action of the false bottom to discharge the load when the sides are raised I will describe the means employed for raising and lowering said sides.

At the respective ends of each side 0 of the car two arms Z are secured and project therefrom, said arms being made at their free ends with bosses Z, having screw-threaded perforations Z for the accommodation of a vertical screw F. Each screw F has secured to its lower end a round bearing-block F, which has its seat in a socket 1%, made in the platform of the car. In each socket m a metallic plate m is placed, and between each metallic plate m and the bearing-blocks on the screws F antifriction balls or rollers m are located, whereby to reduce friction when said screws are turned. Between the ends of each screw F teeth are made to produce a ratchet-wheel G. The arms n n of a lever H are loosely connected with each screw E above and below the ratchet-wheel G, and between said arms n n a double dog 0 is pivotally connected, said dog having an arm n by which to turn it to cause one or the other edge thereof to engage the ratchet-wheel, according to the direction in which the sides of the car are to be moved, up or down. Each dog will be retained in proper mesh with its respective ratchet-wheel by means of a spring n Each lever H is made in its end with a socket for the reception of an arm H to be grasped by the operator. The false bottom having been placed in the car, as above described, and the ear hav-' ing been loaded with gravel or other loose material, and it being desired to discharge the contents of the car, the levers or jacks at both ends of one side of the car will be operated to cause that side of the car to be raised. This operation will be continued until the side of the car shall have been raised just above the edge of one of the sections h of the false bottom. This leaves one section of the bottom and the load thereon supported solely on the inwardly-inclined feet, and'as the preponderance of weight is then on the unsupported side of the section of the bottom the latter slides outwardly and comes to a rest in an inclined position with its outer side edge adjacent to or in contact with the standards I), thus permitting a part of the contents of the car to flow out between the lower edge of the side of the car and the bottom thereof. The remainder of the contents will then be discharged at the other side of the car by raising the other side 0 in the same manner as above explained.

Each side 0 of the car is provided with two (more or less) perforations p at points below the normal position of the false bottom, said perforations being preferably faced with metallic plates 13' bolted to the outer face of the sides of the car and preferably extending to the top edges thereof.

When it is desired to discharge the entire contents of the car at one side thereof, pins (1 (shown in dotted lines, Fig. 4c) are passed through the perforations p in the side 0 at the opposite side of the car from which the gravel or other material is to be discharged. The side 0 of the car having the pins therein will now be raised by means of the jacks it follows that when one section h, with its hinged section h, falls outwardly the hinged portion h of the other section falls in the same direction, thus destroying the central ridge and forming a practically straight bottom, inclined from one side of the car to the,

other.

It may be desired to support the narrow sections it of thefalse bottom while the car is being loaded, and for this purpose pins 1" may be inserted through perforations in the ends of the car,the free ends of said pins being disposed under said narrow sections h. When the car shall have been loaded, these pins may be removed, the load or weight on the sections it being sufficient to hold them in their inclined positions.

Should it be desired to employ the car for conveying large articles or other heavy freight which could not be discharged in the manner above explained and with which the false bottom would be useless, the latter can be removed and placed parallel with the inner faces of the sides 0, where they will be held by means of clamps 8, said clamps comprising two hooks, one to receive the sides 0 and the other to receive the false bottom. The feet on the false bottom and the ears or brackets which support-them will be removed and placed in the boot A, as will also the plates or brackets g. The car will then be in condition to receive any large freight which it may be desired to place therein.

My improvements are very simple in con struction, comparatively cheap to manufacture, simple and easy of application, and effectual inall respects in the performance of their functions.

It is evident that my improvements are equally well adapted to large cars, push-cars, wagons, carts, and even to grain-elevators or any apparatus in which dumping or discharging devices are employed.

Numerous slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but,
